A former New Berlin high school teacher pleaded guilty on Thursday to charges she had a sexual relationship with a student.

Sara Domres, 28, faces up to six years in prison and six years of probation. Her sentencing was scheduled for Sept. 30.

Her guilty plea came as part of a deal with prosecutors.

Domres was charged in April of two class H felonies. Police believe she and her former English student had a relationship for nearly a year before some of the boy's friends reported their concerns to authorities.
